You have to consider the whole context:
Zec 13:7 Awake, O sword, against my shepherd, and against the man that is my fellow, saith the LORD of hosts: smite the shepherd, and the sheep shall be scattered: and I will turn mine hand upon the little ones.
Zec 14:8 And it shall be in that day, that living waters shall go out from Jerusalem; half of them toward the former sea, and half of them toward the hinder sea: in summer and in winter shall it be.
The living waters have been flowing since Pentecost - so this place the events "1/3" surviving the war and destruction of Jerusalem in 1st century AD
The "smiting of the shepherd" is quoted by Jesus:
Mat 26:31 Then saith Jesus unto them, All ye shall be offended because of me this night: for it is written, I will smite the shepherd, and the sheep of the flock shall be scattered abroad.
There is no justification for transporting Zech 13 and 14 2000 years past the 1st century AD.
